Our GPU test bench got an upgrade a couple of months ago, and due to various life happenings (such as moving to another city), it never got used. As it turns out, that was a bit of a blessing, as I never considered the fact that it didn't have PCIe 3.0, the latest standard that both AMD and NVIDIA are shipping products for. Second, I'll soon be heading up our hard drive testing, and for that, I needed a good SATA 6 controller - which the X58 motherboard I updated our rig with didn't have (this is why).
